Understanding the Data
The First-Year Player Draft, also known as the Rule 4 Draft, is Major League Baseball's primary mechanism for assigning amateur baseball players, from high schools, colleges, and other amateur baseball clubs, to its teams. The draft order is determined based on the previous season's standings, with the team possessing the worst record receiving the first pick. In addition, teams which lost free agents in the previous off-season may be awarded "compensatory" picks.
Wins Above Replacement (WAR)
WAR measures a player's value in all facets of the game by deciphering how many more wins he's worth than a replacement-level player at his same position (e.g., a Minor League replacement or a readily available fill-in free agent).
